JIG FOR SEPARATING RES.

SPECIFICATION forming part of Letters Patent No. 371,427, dated October11, 1887 Application filed September 30, 1886. Serial No. 214.908. (Nomodel.)

To tZZl whom it may concern:

Be it known that I, GURDoN GONKLING, a citizen of the United States,residing at Glens Falls, in the county of Varren and State of New York,have invented new and useful Improvements in Jigs for Separating Orcs,of which the following is a speeitica-tion.

The object of my invention is to apply to a central discharge-jig meansfor controlling the quantity of water used in the operation. Ihepeculiar and novel devices and combinations which I use for this purposeare pointed out in the following specification and claims, andillustrated in the accompanying drawings, in which- Figure l representsa vertical central section of a central discharge-jig constructedaccording to my invention. Fig. 2 is a side View of the dam and gatewith discharge-tube in sec tion, the parts being shown on a larger scalethan the previous iigurc. Fig. 2* is another side view of the same. Fig.3 is a horizontal section ofthe same in the plane x x, Fig. 2. Fig. etis a sectional side view of a modification. Fig. 5 is a horizontalsection of the same in the plane y y, Fig. 4.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a tub, of wood or othersuitable material, in which is placed the jig B. From the bottoni ofthisjig extends the tube C, which is open above and below, and whichpasses through a stufing-box, D, secured to the tub A in any desirablemanner. In the tube G is tirmly secured a cross-shaped step-block, c, inwhich is fastened the shaft Z), that extends to the jig B, which issuspended by means of straps c from a lever, G. The straps c areattached to a sleeved, which tits the shaft b loosely, but is connedthereon by the collars c e', so that said shaft can turn freely in thesleeve; but if the sleeve is raised or depressed the shaft, togetherwith thejig, must follow. The upper end of the shaft Z) extends througha bevel-wl1eel,f, to which it is connected by a feather or key, and saidwheel receives a revolving mot-ion by a bevel-wheeLg, mounted on thedriving-shaft. The lever G serves to impart to the jig arising-and-falling or jumping motion in a manner well known.

The bottoni of tliejig is made in the form of asieve, the openings ofwhich are of a size suitable to the material to be separated. The ore tobe separated is fed into thejig so as to form an ore-bed about equal indepth to the height ofthe annular ange k, projecting above the sieve,and as the jig receives motion the heavy particles settle down andescape through the meshes of the sieve into the tub, while the lightparticles, which are the waste, are dis charged with the water throughthe central discharge-tube, C.

rIhe water is introduced into the tub A through a pipe, I, until itrises to a level of three or more inches above the surface of theore-bed in the jig. Into the ange k of the sieve is fitted the dam Z,which is suspended by means ot' rods m m from a ring-plate, a. This ring-plate turns loosely in a groove formed in a nut, o, which tits ascrew-thread on the shaft Z). By turning the nut o, therefore, the dam Zcan be adjusted up or down, according to the depth of water over theore-bed on the sieve. When the jig` is caused to revolve andjump up anddown, the waste, together with a quantity of water, is carried over theedge ot' the dam and down through the tube C, and if the mouth of thedam Z is cpen and unobstructed a very large quantity ot' water isrequired to effect the separation of a comparatively small quantity ofore.

For the purpose of controlling the quantity of water which dischargesthrough the mouth of the dam, I combine with said dam a movable gate, p.In the example shown in Figs. l, 2, 2*, and 8, the movable gate p titsthe interior ofthe dam Z, and the dam is made of such a height that itstop edge will always be above the level of the water on the ore-bed. Inthe sides of the dam are openings (one or more) Z', and on the upperedge of the dam are formed two inclines, Z2, and the gate p ispro. videdwith two projections, p', which bear upon the inclines Z2, and one orboth of which are provided with a set-screw, p2, to hold the gate in anyposition to which it may be adjusted. The gate, being turned, is raisedor lowered, and the openings Z in the dam are uncovered to a greater orless extent. By adjusting the gate in the proper position and securingit in such position by means of the setscrew p, the discharge of thewater through lOO the openings Z can be regulated'. The gate p may,however, be left out, and in this case the dam will be adjusted up auddown, so that the openings Z in its sides will be closed more or less bythe flange 7c ofthe sieve, and the quantity of water which dischargesthrough these openings can thus be regulated.

In the example shown in Figs. 4 and 5 the movable gate 19 consists of atube, the diameter of which is equal to. that of the dam Z, and it isheld in position by means ot' hooks p3, which slide up and down on therods m m, and are provided with clamping-nuts p4. By adjusting the gatecloser to or farther from the top edge of the darn the quantity of waterwhich is permitted to discharge through the dam can be regulated. l

By combining with the dam Z thev movable gate p, I am enabled to'workthejig with a greater depth of water above the ore-bed than heretofore,and at the same time the quantity of water which discharges can becontrolled, so that no more water is wasted than is absolutel ynecessary to effect the desi red separation.

What I claim as new, and desire to secure by Letters Patent, is-
